OPHTHALMIC MOUNTING.

Original application filed June 13, 1921, Serial No. 477,146. Divided and this application filed September 2. 1922. Serial No. 585,910.

This application is a division of application Serial No. 477,146, filed June 13, 1921, relating to ophthalmic mountings.

The chief object of the present invention is to provide an improved ophthalmic mounting of the non-metallic type. Other objects will appear hereinafter.

\Vith the above objects in view, the invention consists more particularly of the improved ophthalmic mounting hereinafter described, illustrated in the accompanying drawings, and defined in the appended claims.

In the drawings, Fig. 1 is a fragmentary front elevation of an ophthalmic mounting constructed according to a preferred embodiment of the present invention; Figs. 2 and 3 are sections taken, respectively, upon the lines 2-2 and 33 of Fig. 1, looking in the direction of the arrows; Fig. 4 illustrates the invention applied to folding eyeglasses; and Fig. 5 is a Section taken upon the line 5-5 of Fig. 4, looking in the direction of the arrows.

The invention is for illustrative purposes shown in connection with an ophthalmic mounting comprising a metal nose bridge 62 secured to a non-metallic lens rim 64. A nose-bridge terminal plate66, having beveled walls 68, is forced into a previously formed, provided upon the non1netallic rim 64. A rivet or screw is employed to securely fasten the parts together. Preferably, the end of the rivet or screw 72 that lies in the lens-receiving groove- T6 is previously split, and the split portions are forced apart and into the non-metallic material, as shown at 74, after the rivet is mounted in place. This method of securing the rivet or screw in place may be readily.

and scope of the invention will readily suggest then'iselves to persons skilled in the art. The above description is therefore intended to be illustrative and not restrictive, and it is desired that the appended claims be broadly construed, unlimited except in so far as limitations may be imposed by the prior art.

What is claimed as new is:

1. An ophthalmic mounting comprising a non-metallic member having a lens-receiving groove, a member joined to the non-metallic member, and a split metal member forjoining them together, the metal member being mounted in the non-metallic member and having the split parts diverging and extend- I ing into the groove and forced into the nonmetallic material of the non-metallic mem her at the groove to conform to the shape of the groove.

2. An ophthalmic mounting comprising a non-metallic member having a lens-receiving groove that is angular in cross section, a metal member, and an element extending through the metal member and the nonmetallic member and into-the lens-receiving groove to secure the metal member to the non-metallic member, an end. of the element being split and the split parts being forced apart and into the non-metallic material of the non-metallic member to conform to the angle of the lens-receiving groove.

In testimony whereof, We have hereunto subscribed our names this 30th day of August, 1922.
